OverviewThis Web Mapping Application provides the ability to print maps based on FEMA's National Flood Hazard Layer (NFHL) dataset. This application should only be used for areas where digital Flood Insurance Rate Map (FIRM) data is available; for other areas it is recommended that users use printing tools available at the MSC.FEMA's National Flood Hazard LayerThe National Flood Hazard Layer (NFHL) dataset represents the current effective flood data for the country, where maps have been modernized.  It is a compilation of effective Flood Insurance Rate Map (FIRM) databases and Letters of Map Change (LOMCs). The NFHL is updated as studies go effective. For more information, visit FEMA's Map Service Center (MSC). Base Map ConsiderationsThe default base map is from a USGS service and conforms to FEMA's specification for horizontal accuracy.  This base map  from The National Map (TNM) consists of National Agriculture Imagery Program (NAIP) and high resolution orthoimagery (HRO) that combine the visual attributes of an aerial photograph with the spatial accuracy and reliability of a map.   This map should be considered the best online resource to use for official National Flood Insurance Program (NFIP) purposes when determining locations in relation to regulatory flood hazard information.  If a different base map is used with the NFHL, the accuracy specification may not be met and the resulting map should be used for general reference only, and not official NFIP purposes.Users can download a simplified base map from the USGS service via: https://viewer.nationalmap.gov/services/ For the specifics of FEMA’s policy on the use of digital flood hazard data for NFIP purposes see standards 605 and 606 in FEMA Policy: Standards for Flood Risk Analysis and Mapping available from Guidelines and Standards for Flood Risk Analysis and Mapping Activities Under the Risk MAP Program | FEMA.govFurther InformationFor more flood map data, tool, and viewing options, visit National Flood Hazard Layer | FEMA.gov
